4-(3-Benzyloxy-propyl)-6-trimethylstannanyl-pyrimidine-2-carbonitrile → 4-(3-Benzyloxy-propyl)-6-(3-methylsulphamoyl-5-trifluoromethyl-phenyl)-pyrimidine-2-carbonitrile

Reaction Steps

3-Bromo-N-methyl-5-trifluoromethyl-benzenesulphonamide (37 mg), 4-(3-benzyloxy-propyl)-6-trimethylstannanyl-pyrimidine-2-carbonitrile (40 mg) and dichlorobis(triphenylphosphine)palladium(II) (7 mg) in DMF (1 mL) were heated in a microwave to 180° C. for five minutes. The mixture was diluted with ethyl acetate (20 mL) and washed with water (3×20 mL). Organics were separated, dried over sodium sulphate, filtered, and solvent was removed under reduced pressure to yield crude product. Purification by preparative-HPLC afforded 4-(3-benzyloxy-propyl)-6-(3-methylsulphamoyl-5-trifluoromethyl-phenyl)-pyrimidine-2-carbonitrile (16.5 mg).
